Migrating your mailbox from ISG to Exchange
Contents
Introduction
Some professorships and institutes at D-ITET have decided to use the exchange mail server instead of the D-ITET mail server. This guide is intended to show you the steps to be able to move your mail account to the exchange server. If certain steps in these instructions are unclear, please contact your technical contact first or create a ticket by sending an email to <support@ee.ethz.ch>.
Pre-migration steps
There are some limitations on the Exchange Server which mean that not all emails can be transferred. You must have completed the following steps before you start the actual migration itself:
Quota - In contrast to our mail server, your mailbox on the exchange server has a quota. This quota applies to your mailbox and all folders in it. Employees usually have a storage space limit of 5GB on the exchange server. If your technical contact tells you that you need to reduce the amount of data, you can either delete emails you no longer need or you can export them first, before you delete them afterwards. In Thunderbird you could use the following steps to export emails:
- Right click on the respective mail and select "Save as ..."
- Select the storage location. The mail is saved as an .eml file, which is opened and displayed again in Thunderbird with a double click.
- Afterwards you can delete the email.
If you have to export a lot of emails, you should use an export tool. For Thunderbird there is for example the ImportExportTools NG by Christopher Leidigh which can export many selectable mails in addition to the EML format also in PDF, HTML or plain text. You can find short instructions for this plugin here
Mail item limit - Every object on the Exchange server (email, contact, appointment entry, etc.) is an item. The Informatik Dienste have defined an upper limit of 50,000 items. Above this limit, performance problems can and will occur with your own mail account.

The steps to export your mails are the same as described under quota.
